Title: Method of immobilizing and crosslinking proteins and other molecules and uses thereof
Inventor: ANDERSON LESLIE D
IPC: C07K19/00
Filed: 1992-01-29
Abstract: ABSTRACT    The invention provides a method for immobilizing and purifying proteins. The invention further provides a method for the formation of a kinetically inert complex between a transition metal ion and a Biologically Active Molecule or reporter group which possesses a metal binding site to form a kinetically inert complex between the CP-protein and the bound metal ion.  This kinetically inert [immobilized metal/CP-protein] complex provides a component of an assay system useful for studying the interaction of any of a variety of ligands with the immobilized CP-protein.  The invention further provides a method of purifying IPs or receptors on a Solid Support.  Immobilization of IPs or other Biologically Active Molecules utilizing the methodology of the instant invention enables one to orient these molecules so as to maximize exposure of the antigen or ligand binding site in an affinity chromatography system.  Furthermore the invention provides a method of forming heterodimeric, homodimeric or multimeric complexes by crosslinking two or more Biologically Active Molecules or reporter groups with metal binding sites.

Title: Slow release syneresing polymeric drug delivery device
Inventor: HSU TERRY T-P
IPC: A01N25/10
Filed: 1992-10-14
Abstract: TITLE OF THE INVENTION SLOW RELEASE SYNERESING POLYMERIC DRUG DELIVERY DEVICE            ABSTRACT OF THE DISCLOSURE There is disclosed a slow release drug delivery device for the prolonged administration of topically active medicines which consists of a vehicle in which water is soluble and in which is dissolved the topically active drug which is formed into a stable organogel with a polymer matrix with a very low water absorbing capability.  The organogel, in the presence of water or atmospheric water vapor, slowly imbibes such water into the vehicle and by doing so the vehicle becomes incompatible with the matrix and is slowly expelled therefrom.  The vehicle dissolves the drug and the vehicle/drug combination is slowly pumped out of the polymeric matrix with substantially linear drug delivery occurring for periods in excess of 6 months.  The drug delivery device may be used to administer drugs topically, as a collar or trans dermal patch, orally, as a slow delivery device, particularly as a ruminal bolus,, or as a suppository or a subcutaneous implant.  The preferred form for the drug delivery device is as a flea and tick collar for household pets and the preferred active drug is selected from the avermectin and milbemycin families of active antiparasitic agents.

IPC: B65D88/46
Filed: 1991-05-10
Abstract: A rim space (20) sealing device comprising a peripheral sealing ring of over-lapped shoe segments (36) attached to a floating cover within a storage tank (22). Spring loaded hanger-pushers (68) and horizontal springs (74) keep the peripheral sealing ring of shoe segments (36) pressed against the tank wall (22) and also keep the floating cover (24) centered within the tank (22). The space (20) between the peripheral seal-ing ring of shoe segments (36) and the floating cover (24) is covered by a flexible fabric (94) that prevents products loss. Vertical movement of the individual shoe segments (36) over each other is prevented by a series of circumferentially arranged rods (82). The over-lap of the shoe segments (36) is restricted by a series of bars (44) forming expansion-contraction spaces (48).

Abstract: ABSTRACT A conduit and method of making a conduit for an underground conduit system, where the conduits are protected from ultra-violet rays, the conduit system being able to transport and insulate a variety of materials including, but not limited to, fluids and wires. The assembled conduits being able to be located underground to support the weight of the soil without crushing the insulating layer and thus destroying the insulating qualities of the insulating layer. The assembled conduits coact to protect the interior of the conduit system from moisture located radially outward of the conduit system. The conduits have an interior rigid pipe which is used to carry fluids and wires  and the like, surrounding the interior rigid pipe is an annular insulating layer which acts as an insulator to prevent fluids from freezing in the pipe by retaining the heat of the fluid in the pipe and, a waterproof seal mechanism to form the annular insulating layers of adjacent conduits into a leakproof engagement with a flexible cylindrical sleeve surrounding the annular insulating layer with the flexible cylindrical sleeve extending beyond the ends of the insulating layer to form a protective covering to keep the ends of the conduits free of contaminates when the conduit is being stored.

Title: Combined speed and depth sensor transducer
Inventor: MASRELIEZ KARL G
IPC: G01S7/521
Filed: 1993-02-12
Abstract: COMBINED SPEED AND DEPTH SENSOR TRANSDUCER                  Abstract of the Disclosure A combined speed and depth transducer adapted to be mounted  flush  in the  hull  of  a  ship.   An  acoustic depth transducer is mounted piggyback on top of an acoustic speed transducer  within  a  single  housing.    A  base  plate  is sandwiched  between  the  depth  transducer  and the  speed transducer.   The dimensions and frequency of transmission of the  transducers  are  selected  to  prevent  ringing  in  one transducer that may be caused by the acoustic wave of the other transducer.   The base plate 40 is constructed to damp the acoustic wave transmitted by the speed transducer and be transparent to the  acoustic wave transmitted by the  depth transducer.   Having the depth and speed transducers mounted within a common housing, and flush with the hull of the ship, provides the advantage of having to make only a single hole in the hull as well as having a low drag.

Abstract: A plurality of optical fiber ribbons, each containing a plurality of optical fibers, are loosely enclosed in a substantially fluid impervious tube of plastic material.  A plurality of such ribbon enclosing tubes are wound in S or Z fashion around a central structural member which can be covered with a plastic material.  The so-wound tubes are encircled by threads or tape to hold them in place, and a covering of helically wound yarns is applied around the tubes to provide strength.  A plastic sheath is applied over the yarns, and if desired the sheath is covered with other layers.  Any otherwise empty spaces within the tubes and between the sheath and the tubes is filled with a water blocking material which permits the ribbons to move with respect to the enclosing tubes and which permits the tubes to move with respect to the sheath and the central member.

Title: Automatic dispenser for paper towels severable from a continuous roll
Inventor: NIADA GIANANDREA
IPC: A47K10/36
Filed: 1993-04-07
Abstract: ABSTRACT          An automatic dispenser for paper towels shaped in strips of an appropriate length   severable from a continuous feed roll, outputs from the device a portion of paper of an appropriate length cutting it by means of a station-ary blade  located in a  less  accessible area of the apparatus  for  user's  safety  reasons.  Dispensing  is controlled by means of a pushbutton, photoelectric cell or the like, which actuates a switch for supplying power to a motor during a time period predetermined by means of a timer, and which therefore causes rotation of a dragging roller adapted to cause a certain extent of un-rolling of the feed roll.  Said timer inhibits dispens-ing, in case the switch is kept continuously actuated, before a predetermined pause interval has elapsed.

Abstract: 57,350 ABSTRACT OF THE DISCLOSURE           A  method  of  designing  and  manufacturing  an electrical generator which has a specific target power output rating includes the steps of selecting one of a predetermined, standardized set of diameters for the rotor, stator and frame of the generator; and subsequently selecting the length of the generator stator core and one of several standardized number of stator coil slots based on the target power rating and voltage of the generator.  The invention permits standardized generator components which are specific to the selected set of diameters to be used during assembly of the generator, instead of customized components, which results in reduced design and manufacturing costs per generator.
